AI Technical Summary

Benefits of technology

The design allows for a more compact and lower-height printer module, enabling the reduction of the printing apparatus's size while maintaining functionality, and reduces fabrication costs by eliminating the need for a hook member in the platen roller locking mechanism.

Problems solved by technology

For this reason, it was difficult to reduce the size of the printer module and lower the height of the printer module.
Consequently, it was difficult to reduce the size of the printing apparatus, and particularly difficult to lower the height of the printing apparatus.

first embodiment

[0046]FIGS. 1A and 1B are a perspective view and a cross sectional side view illustrating a credit card settlement apparatus 1 which is an example of an electronic apparatus applied with a thermal printer module 30 in a first embodiment of the present invention. X1-X2 corresponds to a width direction, Y1-Y2 corresponds to a longitudinal direction, and Z1-Z2 corresponds to a height direction.

[0047]The credit card settlement apparatus 1 is a portable type apparatus having a flat parallelepiped (or box) shape, and may be held by one hand of an operator while the operator operates the credit card settlement apparatus 1 with the other hand. The credit card settlement apparatus 1 has an upper surface 2 provided with a credit card reader 3 which magnetically reads a number or the like of a credit card (not illustrated) that is scanned, a liquid crystal display (LCD) 4, and a keypad 5. The credit card reader 3 is provided on the X2 side of the upper surface 2, the LCD 4 is provided on the Y...

second embodiment

[0102]FIG. 15 is a cross sectional view illustrating a part of a thermal printing apparatus 20A of a credit card settlement apparatus 1A applied with a thermal printer module 30A in a second embodiment of the present invention. The arrangement of the pulse motor 68 in the thermal printing apparatus 20A is different from that of the thermal printing apparatus 20 illustrated in FIG. 2. In the thermal printing apparatus 20A, the pulse motor 68 is arranged inside the credit card settlement apparatus 1A.

[0103]FIG. 16 is a disassembled perspective view of the thermal printer module 30A. The thermal printer module 30A includes the thermal head assembly 31, a main assembly 50A, and the platen roller assembly 70. The main assembly 50A has a structure different from that of the main assembly 50 illustrated in FIG. 4.

[0104]The main assembly 50A has a frame 51A including a box part 53A. The box part 53A has an extension part 110 which extends in the Z1 direction. A side plate part 55A also has ...

third embodiment

[0107]FIG. 17 is a cross sectional view illustrating a part of a thermal printing apparatus 20B of a credit card settlement apparatus 1B applied with a thermal printer module 30B in a third embodiment of the present invention. The arrangement of the pulse motor 68 in the thermal printing apparatus 20B is different from that of the thermal printing apparatus 20 illustrated in FIG. 2.

[0108]FIG. 18 is a disassembled perspective view of the thermal printer module 30B. The thermal printer module 30B includes the thermal head assembly 31, a main assembly 50B, and the platen roller assembly 70. The main assembly 50B has a structure different from that of the main assembly 50 illustrated in FIG. 4.

[0109]The main assembly 50B has a frame 51B including a box part 538. The box part 53B has an extension part 120 which extends in the Y1 direction. A side plate part 558 also has an extension part 121 extending in the Y1 direction.

[0110]The pulse motor 68 is mounted on the extension part 121 at a ...

Abstract

A printer module for a clam-shell type printing apparatus having a lid that opens and closes with respect to a housing, includes a head assembly including a head and mounted on the housing, a platen roller mounted on the lid, and a main assembly including a frame and a motor mounted on the frame to rotate the platen roller. The main assembly is arranged to cover the head assembly and is mounted on the housing.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of a Japanese Patent Application No. 2008-311406 filed on Dec. 5, 2008, in the Japanese Patent Office, the disclosure of which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention generally relates to printer modules and electronic apparatuses, and more particularly to a printer module applicable to a clam-shell type printing apparatus, and an electronic apparatus having such a printer module.[0004]2. Description of the Related Art[0005]The clam-shell type printing apparatus is formed by a main body and a lid that is configured to open and close with respect to the main body. Each of the main body and the lid is mounted with a module. The modules of the main body and the lid are connected to form the printing apparatus when the lid is closed.[0006]The clam-shell type printing apparatus is employed in both desk-top electronic apparatuse...
